-Required properties:
- - compatible : Should be one of
- "nxp,sc18is602"
- "nxp,sc18is602b"
- "nxp,sc18is603"
- - reg: I2C bus address
-
-Optional properties:
- - clock-frequency : external oscillator clock frequency. If not
- specified, the SC18IS602 default frequency (7372000) will be used.
-
-The clock-frequency property is relevant and needed only if the chip has an
-external oscillator (SC18IS603).
-
-Example:
-
- sc18is603@28 {
- compatible = "nxp,sc18is603";
- reg = <0x28>;
- clock-frequency = <14744000>;
- }
